Potential used buyer - battery life concerns

[anko]

Will be nice to know the report form Anko of his cells when the car is shown on dash as fully discharged (which in reality is 25 to 30% of SOC left)

You were asking ....? This is at 29%. All cells are within a 0.011 volt range. That is not to bad, is it?

Thanks a lot Anko

So apparently your cells are all ageing in a similar way

That is good to know that Mitsubishi and/or the battery supplier did a good QC in production

If one or two would have been weaker then other ... maybe would have been a better result, since you would know that by changing only these you could restore the pack to a much better state.

PS: Now that you know that the weaker cell is #71 ... you could eventually check immediately after fully charge the pack .. it this is still the weaker, or it is going to be one with the highest voltage ... 0.011V does not sound a lot .. but Lithium battery under 3.80v tend to stabilize the voltage under load .. only under 3.70v they start to lose their voltage much faster

PPS: Another way to see the weaker cell, it is to check the delta voltage under load ... but since you have tons of different monitoring on your car, I guess you may know already which cells are the bad one, and how much they different from the other

PPPS: My new Chinese LM375 ODB2 did work fine on Torque Pro ... but failed with EvBatMon ... so now I'm waiting for the expensive OBDLink LX from Amazon.de ... I may contend to you the ownership of the worst PHEV battery in this forum ...
